Merge branch 'pfc' of...

Merge branch 'pfc' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/sh-pinmux

From Simon Horman. Based on agreement between me, Paul Mundt, Linus
Walleij and Simon, we're mergning this large branch of pinctrl conversion
through arm-soc, even though it contains the corresponding conversions
for arch/sh. Main reason for this is tight dependencies (that will now
mostly be broken) between the arch/sh and mach-shmobile implementations.

There will be more of this in 3.10 to do device-tree bindings, but this is
the initial conversion.

* 'pfc' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas: (80 commits)
  sh-pfc: Move sh_pfc.h from include/linux/ to driver directory
  sh-pfc: Remove pinmux_info definition
  sh: Remove unused sh_pfc_register_info() function
  sh: shx3: pinmux: Use driver-provided pinmux info
  sh: sh7786: pinmux: Use driver-provided pinmux info
  sh: sh7785: pinmux: Use driver-provided pinmux info
  sh: sh7757: pinmux: Use driver-provided pinmux info
  sh: sh7734: pinmux: Use driver-provided pinmux info
